English abstract

User interfaces of web based online public access catalogs (OPACs) of academic, special, public and national libraries in countries belonging to Mercosur (Argentina, Brazil, Paraguay, Uruguay) are studied to provide a diagnosis of the situation of bibliographic description, subject analisis, help messages and bibliographic display. A cuali-cuantitative methodology is adopted and a checklist of systems functions created by Hildreth (1982) is updated and used as data collection tool. The resulting 38 closed questions checklist has allowed to observe the frequency of appearance of the basic functions of four areas: Area I – operational control; Area II, search formulation control and access points; Area III ,output control; and IV, user assistance: information and instruction. The study is carried out on the information obtained from 297 information units. Strata are delimited according to type of software, type of library and country. Chi square, Odds Ratio and multinomial logistic regression are applied to results. This analysis confirms the presence of significative differences according to the delimited strata and shows that most of the OPACs surveyed offer minimum capabilities.

Spanish abstract

Se analizan las interfaces de usuario de los catálogos en línea de acceso público (OPACs) en entorno web de las bibliotecas universitarias, especializadas, públicas y nacionales de los países parte del Mercosur (Argentina, Brasil, Paraguay, Uruguay), para elaborar un diagnóstico de situación sobre: descripción bibliográfica, análisis temático, mensajes de ayuda al usuario, visualización de datos bibliográficos. Se adopta una metodología cuali-cuantitativa, se utiliza como instrumento de recolección de datos la lista de funcionalidades del sistema que proporciona Hildreth (1982), se actualiza, se obtiene un formulario que permite, mediante 38 preguntas cerradas, observar la frecuencia de aparición de las funcionalidades básicas propias de cuatro áreas: Área I - control de operaciones; Área II - control de formulación de la búsqueda y puntos de acceso; Área III - control de salida y Área IV - asistencia al usuario: información e instrucción. Se trabaja con la información correspondiente a 297 unidades. Se delimitan estratos por tipo de software, tipo de biblioteca y país. Se aplican a los resultados las pruebas de Chi-cuadrado, Odds ratio y regresión logística multinomial. El análisis corrobora la existencia de diferencias significativas en cada uno de los estratos y verifica que la mayoría de los OPACs relevados brindan prestaciones mínimas.
